Which is better? In price and quality?

Out of these 2 brands, AlvoDerm for sure!!!! Purina One is crap food. Brewers Rice is the outer shell of the rice kernel that is removed before packaging for humans, and has NO nutritional value whatsoever!!! Corn Gluten, Poultry fat, and Animal Fat, animal digest is all bad and should not be in dog food!! Your dogs will have a nice coat on the AvoDerm as well!! Take Care!!
